Specification of Letters Patent.

To all 20710172. it may concern:

Be it known that I, PAUL HAN-son, a citi zen of the United States,residing at Wild Horse, in the county of Cheyenne, in the State ofColorado, have invented certain new and useful Improvements inButterMaking Machines, of which the following is a specification.

This invention relates to butter making machines, and more particularlyto ma chines of this class which are adapted to be operated bymechanical power.

The principal object of the invention is to provide an improved means ofthe class described in which the working parts within the drum may bereadily removed for cleaning, repairing, etc., and which is effectiveand efficient in operation.

A further object of the invention is to provide an improved machine ofthe class described which may be operated at different speeds while thedriving shaft is being driven at the same speed.

For the attainment of these ends, and the accomplishment of other newand useful objects, as will appear, the invention consists in thefeatures of novelty in the construction, combination and arrangement ofthe several parts generally shown in the accompanying drawings anddescribed in the specification, but more particularly pointed out in theappended claims.

In the drawings Figure 1 is an end elevation of a machine constructed.in accordance with the principles of the invention and as viewed on theline 11 of Fig. 4: Fig. 2 is an end elevation of the drum and theoperating gear as taken on the line 2-2 of Fig. 4; Fig. 3 is a sideelevation of the machine; Fig. 1 is a detail sectional view of theoperating gear; Fig. 5 is a sectional view on the vertical line 5-5 ofFig. 7 through the drum showing a section of the door, jambs, andpacking, and the butter working roller and jacks on one side of thedrum; Fig. 6 is a detail sectional view of the butter working roller atits driving end, showing the packing connections; Fig. 7 is a crosssectional view through the drum: Fig. 8 is a detail sectional view ofthe roller at the end and the means for adjusting a longitudinalposition of the roller; Fig. 9 is a detail view of the planetary gearingwhich transmits mo tion at reduced speed; Fig. 10 is a detail view of aplanetary gearing when locked solid with the shaft; Fig. 11 is a detailview partly in section of one of the pinions of the planetary gear, andthe end of a lever in engagement with one of the lugs or housings of theplanetary pinions; Fig. 12 is a detail view partly in section 011 theline 12-12 of Fig. 4, showing the means for adjusting the drum bearing.

Referring now more particularly to the drawings, the drum 15, which maybe of any desired or suitable shape, but preferably is substantiallycylindrical, and is rotatably mounted upon its axis in the bearingsupports 16. These bearing supports 16, together with cross pieces 17and braces 18, are formed of any suitable material and constitute asupporting frame for the drum and the operating mechanism therefor.Preferably, and in the present exemplification of the invention, thedrum is composed of wood and hoops 19 are provided to hold the sides ofthe drum securely in position Extending longitudinally of the drum is anopening having a door or closure 20, with an outer surface ofsubstantially the same curvature as the outer surface of the drum, sothat when the door is locked in position the drum and the door willpresent a substantially cylindrical exterior. The drum 15 is formed withjamb members 21 which present a substantially plane opening for the dooror closure 20. In the lower face of the door is a groove which isadapted to receive packing material 22 which constitutes an air tightconstruction when the door 20 is locked in place.

Disposed within the drum 16 is a butter working roller 23,preferably'formed with extending lips, as shown in Fig. 7. This rolleris preferably mounted upon the same axis as the drum, and has a drivingshaft 2 1 secured to it by a thumb screw 25, which ex tends beyond thebearing support of the drum.

Positioned within the drum and secured to the ends thereof are shelfsupporting brackets 26-27. One of these brackets as 26 is disposed withone end adjacent the side of the door opening of the drum, the other endextending adjacent the center of the drum. This bracket is formed with adepression 28, at the inner end thereof to receive and retain a shelf. Ashelf for this bracket 26 is formed with. end pieces 29 and slats 30,extending longitudinally of the drum and spaced apart. At the inner endof the shelf and disposed between the end members 29 is a roller 31.This side of the shelf is adapted to be seated in the groove ordepression 23 formed in the bracket 26, and the other side of the shelfis adapted to abut the inner surface of the drum adjacent the dooropening in the drum. The shelf is locked in position by means of a catch32, which is movable into engagement with the end of the drum. To removethe shelf from the drum it is necessary only to release the catch 32,and to rotate the shelf outwardly rom its seat upon the shelf bracket 26to take the dotted position shown in Fig. 7. The other shelf bracket 27in the present exemplification of the invention is preferably disposeddiametrically opposite to the shelf bracket 26 and substantiallyparallel with it. At the end of the shelf bracket 27 adjacent the shellof the drum is an abutment 33. The shelf for this bracket 27 issubstantially similar to the other shelf, having end pieces 34 withslats 30 spaced apart and secured thereto, and with a roller 31 mountedthere-between. One side of the shelf is positioned between the abutment33 and the shelf bracket 27 and the other side of the shelf is securedto the bracket by means of a fastening device 35. To remove this shelfit is necessary only to loosen the fastening device 35 and to rotate theshelf until it takes the position shown in dotted outline in Fig. 7,whereby it may be removed through the opening in the drum. It will benoted that these shelves are substantially parallel and that the rollersmounted in the shelves are in a line with the butter working roller 23,the shelves being disposed substantially at right angles to the linepassing through the said rollers.

Referring now more particularly to the mounting of the butter workingroller 23, as shown by Figs. 6 and 8, the drum 15 is provided with abearing member 36 secured thereto and rotatable in a bearing support 37through the bearing member 36, and the bearing support 37, extends ashaft 38 which is preferably threaded into the member 36 and secured inany position by a lock nut 39. The inner end of this shaft 38 is reducedin cross section and extends into the end of the roller 23 where abearing 40 is provided for it. The other end of the roller (see Fig. 6)is provided with a recessed bearing member 41, into which the shaft 24extends, and to which the shaft and the roller are connected by means ofthe thumb screw 25. Extending into the recessed bearing member 41 is asleeve portion 42 of a bearing member 43, which is secured to theoutside of the drum. Disposed within the recess of the member 41,surrounding a shaft 24 and between the bearing member 41, and the sleeve42, is packing material By pressing the roller firmly against the sleeveportion 42 of the bearing member 43 the packing material is compressed,and leaking about the shaft 24 through the opening in the bearing member43 is prevented. The position of the roller in the drum may be variedand adjusted as desired by means of the adjusting device at the otherend of the roller previously described and clearly shown in Fig. 8.

The drum 15 is rotatably mounted in the bearing supports 16 by thebearing member 36 at one end of the drum and by the bearing member 43 atthe other end of the drum. The bearing member 43 is preferably securedto the drum in any suitable manner, and is provided on its outer edgewith gear teeth 44. This bearing member 43 is formed with a sleeveportion 45, extending outwardly from the drum and rotatable in thebearing sleeve 46, which is supported by one of the bearing standards16. This end bearing of the drum is preferably adjustable as shown indetail by Fig. 12. The sleeve member 46 is formed with laterallyextending lugs 47 which are formed with perforations and threaded.Secured to the bearing support 16 is a shield member 43 whichsubstantially surrounds the sleeve 46 and is formed with extendingportions 49, which are adapted to receive the lateral projecting lugs 47of the sleeve 46. The upper side of these extending portions 49 areformed with openings which register with the openings in the lugs 47,both of which are adapted to receive the bolts 50. These bolts 50 bearagainst the lower part of the extending portions 49, so that when thebolts are turned the sleeve 46 will be raised or lowered in accordancewith the movement of the bolts. A locking bar 51 is provided which isadapted to extend over the ends of the bolts and to lock them in anyadjusted position.

Rotatably mounted in the bearing member 43 and extending through thesleeve portion 45 of the bearing member is the driving shaft 24 of thebutter working roller 23. This shaft extends through the sleeve portion45 and is provided at its outer end with a gear 52, which is secured tothe shaft by means of a pin 53 inserted through a slot in the shaft.Interposed between the pin 53 and the sleeve 45 is a washer 54. At theend of the shaft 24 which extends beyond the gear 52, is a washer 55,which is prevented from becoming dislodged from the shaft by means of acotter pin 56, and interposed between the washer and the gear 52 is aspring 57, preferably of the coil spring type. This coil spring 57presses normally against the washer 55 at the end of the shaft, andsince the sleeve member 45 is positively positioned in the bearingsupport, the action of the spring 57 is to tend to press the shaft 24outwardly, thereby maintaining a constant pressure upon the roller 23 inthe drum, to which the shaft is attached, and

being operative to draw the roller and the bearing member 41 of theroller (see Fig. 6) against the sleeve ortion 42 of the bearing member43, and t 'lereby to compress the packing M.

A driving shaft 58 is rotatably mounted in the bearing standardspreferably by means of a bearing sleeve 59, secured to one of thebearing standards 16 adjacent one end of the shaft and in a bearingsupport 16 at the other end of the shaft. Surrounding and freelyrotatable upon the shaft is a driving member 60, rotatable in thebearing sleeve 59. This driving member 60 is preferably formed withdriving portions or gears 61 and 62. The driving portion 61 preferablymeshes with the teeth 4A of the bearing member 43 secured to the end ofthe drum, and the other driving portion 62 is preferably disposedsubstantially in alinement, but not meshing with the gear 52, which issecured to the shaft 24 of the butter working roller. Longitudinallymovable in the hearing frame for the drum is a shaft 63 upon which isfreely mounted a pinion Set. A lever 65 is secured to the shaft 63 bymeans of which the pinion or gear 64 may be moved into and out ofengagement with the driving gears 52 and 62. Partially surrounding theshaft 63 is a shell 66 provided with notches 67 and a lever 65 may bepositioned in one or the other of these notches to hold the gear 64: inengagement with the said gears or to lock the gear 64 out of saidengagement.

Secured to the shaft 58 is a driving gear 68, and freely rotatable uponthe shaft ad jacent the said gear is an internally toothed gearing 69,with its teeth extending substantially in alinement with but remote fromthe driving teeth of the gear 68. Secured to the driving member 60 arepinions 70. which are adapted to mesh both with the driving gear 68 andwith the gear 69. These pinions '70 are provided with housings 71, whichextend over the gearings and secure them to the driving member, one atleast of the housings being provided with an extending lug 72 (see Figs.9, 10 and 11). Pivotally mounted 011 the gear 69 is a lever 73 one endof which is formed with a lateral projection 74, which extends throughan opening in the gear 69, and is adapted to engage the lug 72 of one ofthe housings 71. The normal position of the lever is in engagement withthe lug 72, and it is held in such engagement by means of a resilientmember or spring 75 contained in a housing 76 in the face of the gear69, and pressing against the opposite arm of the lever 73 to hold it insuch engagement. To release the lever 73 from its engagement with thelug 72 the lever 65 which is secured to the shaft 63 is provided with aprojection 77, and this projection is adapted to engage in a notch 78 inthe arm of the lever 73 opposite the projection 7 4. When the lever 65is turned downwardly, the knob 77 engages in the notch 78, raises thelever from its engagement with the lug 72, whereby the gear will belocked against rotation upon the shaft 58.

To form a driving connection for the shaft 58 a drive pulley 79 isfreely mounted to rotate upon the shaft. This driving pulley ispreferably formed with a surface for belt drive and the under face 80 ofthe pulley is formed at a slight inclination. A clutching member 81 ismounted slidably on the hub-81, which is keyed upon the shaft 58,11heclutching member being provided with a circumferential groove 82. Theouter face of the driving member is preferably formed at an inclinationsubstantially the same as the inclination of the inner face of thedriving pulley 79, so that the clutching member 81 may be moved intoengagement with the inner face of the driving pulley. If desired theface of the member 81 may be provided with a yielding member 83, throughwhich the members 79 and 81 may be connected and to prevent wearingthereof. To operate the clutch a lever St is pivetally mounted upon somesuitable part of the frame or supporting structure for the drum, andoperating mechanism and is provided with a bifurcated extremity orextension on both sides of the hub of the clutching member S1 orprojections 85 which enter the groove 82. The movement of the lever 8%about its point of pivotal support is effective to engage or disengagethe clutching member 81 from the drive pulley 7 9 and. thus to completea driving connection between the shaft and the drive pulley 79.

Extending over the gear 62 and the drive pinion 64 is a shield 86, whichmay be formed integral with the shield 48 which extends over the gear52. Pivotally mounted upon this shield 86 is a dog 87 (see Fig. 1),which is adapted to extend through an opening in the shield, and whenrotated about its point of pivotal support to engage the gear 62 to lockthe driving member 60 against rotation, and thereby positioning the drumin any desired fixed posi tion.

In operation the drum may be locked in any desired position tofacilitate the insertion and removal of the parts or materials withinthe drum. lVhen released from this engagement and with the door orclosure 20 in position, the drum may be set in motion through thedriving member 60, which engages the driving teeth lt, and through theplanetary gearing or connections the driving member to the shaft 58. Todrive the drum alone the planetary gearing compris ing the gear 69, thedriving gear 68 and the pinions 70, are locked together by means of thelever 78. To effect the movement of lift the butter working roller atthe same time the drum is rotated, the gear at is moved into engagementwith the gears 52 and 62 by means of the lever 65, whereby the butterworking roller will be rotated simultaneously with the drum but in anopposite direction.

The conditions of operation in churning and in butter working are sodifferent that it is usually desired to rotate the drum and the butterworking roller at a reduced speed when the butter working operation isin progress, for the reason that in working the butter a solid is beingdealt with, while in churning the cream a liquid is being agitated. Toeffect the rotation of the drum and the butter working roller at areduced speed, the planetary gearing is provided, which reduces thespeed of rotation of the drum and the roller without changing the speedof the driving shaft 58. To effect this operation the gearing 69 islocked in position by means of the lever 65, which engages the lever'73, releases the projection 74, and stops the gearing 69, whereupon thepinions which engage with the driving gear 68 and with the teeth of thegearing 69 will be revolved about the gear 68 because of theirengagement with the now fixed gear 69. This, of course, will result in areduction of the speed of the driving member ()0 dependent upon therelative size of. the pinions and gearings, and in the presentexemplification results in a reduction of speed substantially l to l, ascompared to the speed of this member when the planetary gearingis lockedsolid with the shaft. From this description it will be evident that thedrum may be operated alone or it may be operated in connection with thebutter working roller at the same speed, or the drum and the butterworking roller may be operated at a reduced speed, the speed of rotationof the driving shaft 58 remaining the same.
